Title: Improvements in and connected with dough kneading machines
IPC: A21C1/14
Filed: 1923-04-25
Abstract: 219,109. Paton, A. April 25, 1923. Interconnecting guard with starting-gear.-In dough-kneading machines, the cover C is locked while the machine is in motion and the starting-handle I is locked when the cover is open by the use of a block F secured to the framing and having two intersecting holes H<1>, H<2> in which slide rods H, E connected respectively to the lever and cover. The rod E is pivoted to a crank D secured on the end of the hinge-pin A moving with the cover, and the rod H engages a slot in the lever I. Both rods cannot pass through the block F at the same time. In a modification, the rod E is pivoted directly to the cover so as to rise as the cover is lifted, the rod H registering with a hole in the rod E when the cover is closed. Additional security for the cover is provided by a rod K sliding in guides in the cover and pressed by the rod H, when the machine is started, into engagement with a hole in a bracket J on the frame. In this operation the rod H slides through a second fixed bracket J and provides an additional lock for the cover. In order to prevent the insertion of fingers, if it should be possible to lift the cover slightly while the machine is in motion, a flap L is so hinged to the cover edge as to be movable only towards the body of the machine.

Abstract: 126,632. Holm, A. May 6, 1918, [Convention date]. Flanging; dies.-To form turned-over edges on bent metal strips, or pressed metal plates for metal frames, medallions, boxes and cases, &c., the strip or plate is clamped between a die and a matrix, and the edge is bent inwardly over the die by hammering, the die serving as an anvil. As applied to forming two turned-over edges on a bent plate c, the plate is clamped between a matrix a and a die composed of two parts f, g and a tapered core h. While the top edge d is being hammered over the dies f, g, the lower edge is protected by a matrix j and die k. After both edges are turned over, the dies can be readily removed by driving out the core h.

Title: Desulfurization of hydrocarbon oil and catalyst therefor
Inventor: RYLANDER PAUL N
IPC: C10G45/08
Filed: 1957-04-05
Abstract: Refining hydrocarbon oil containing sulphur compounds by contacting in the presence of hydrogen at 600-1000 DEG  F. with a catalyst containing cobaltous ferrite (CoFe2O4).  A hydrogen partial pressure of 50-3000 p.s.i.g., a space velocity of 0.5-20 v/v/hr., and a hydrogen flow rate of 100-10,000 S.C.F./bbl. of feed, may be used. The hydrogen may be supplied from an external source or may be generated in the reactor as in the autofining process, in which case the hydrogen may be recycled and the pressure may be allowed to rise to equilibrium pressure (about 250 p.s.i.g.).  The catalyst may be used on a support, e.g. activated alumina or hydrous alumina gel; a fixed bed or fluidized catalyst may be used.  Hydrocarbon oils referred to are petroleum, coal hydrogenation and shale oils and may be virgin or cracked distillates, catalytically or thermally cracked naphthas, olefinic naphthas, e.g. those produced by coking reduced crudes, and gas oils are referred to.  Cobaltous ferrite may be prepared by mixing a cobalt compound with an iron compound (both compounds being decomposable to the oxide on heating), and heating the mixture at 1000-2000 DEG  F. for 1-24 hours.  Cobalt compounds specified are CoCO3, 2CoCO3.3Co(OH)2.H2O, Co(OH)2, Co2O3.3H2O, CoO, Co3O4, Co2O3, Co(NO3)2.6H2O and CoC2O4; iron compounds referred to are Fe(OH)3, Fe(OH)2, Fe2O3, FeO, Fe3O4, FeF2, FeCl2, FeCl3, Fe(NO3)3.6H2O or Fe(NO3)3.9H2O, Fe(NO)3)2.6H2O, Fe(C3H5O3)2.3H2O (ferrous lactate), Fe2(C2O4)3 (ferric oxalate) and Fe(CHO2)3 (ferric formate).  The mixture of compounds may contain a molar ratio of cobalt to iron of 1 : 10 to 5 : 2, preferably 1 : 2.  The cobaltous ferrite may be used as such or may be pelletted, with or without a support, with a binder, such as 1 or 2 per cent of hydrogenated corn oil or stearic acid, which is subsequently burned off the pellets. The catalyst may be regenerated by burning off the hydrocarbonaceous material therefrom by diluted oxygen such as a mixture of flue gas with air.

[Also in Division F2] A shock neutralizer for a road vehicle comprises a mass 24 mounted on a bar 18 which is connected at its ends to the vehicle chassis 14 and axle 2. The axle is attached to a leaf spring 10 connected at its ends to the chassis 14 by a bracket 12 and a shackle 16. In operation, when the wheel hits a bump A axle 2 and shackle 20 are raised, due to the inertia of mass 24, bar 18 is rotated anticlockwise producing a downward force on the chassis opposing the upward force of the spring. The mass is adjustable and lockable in position by lock bolt 28. The shock neutralizer is also applicable to suspensions using other forms of spring, may be fitted to individual wheels or to the middle of an axle and may be arranged transversely or obliquely of the vehicle.

Abstract: 529,306. Soot-blowers. HOPKINSONS, Ltd., BROWN, R. L., and DALE, W. B. April 15, 1939, No. 11522. [Class 99 (ii) [Also in Group XXXVII] Motors individually operating the blower heads of a soot-blower installation, are controlled sequentially by a contact on a control drum i co-operating with contacts 15, each control circuit being maintained independently of the drum i until a limit switch r, or an emergency switch w is operated, and the driving motor j for the drum being de-energized by closure of contacts 16 at the end of a cycle. While one head is in operation another head may be moved into blowing position and a further head may be withdrawn. The pilot motor j is started by closure of a relay h which is energized when a valve b has been operated to turn on the steam, but is delayed by a dash-pot g. The contacts of the relay h energize a contactor m which maintains itself and effects operation of the motor j. The motor connections are effected by a two-way switch operated by coils 2, 4, interlocked by contacts 5, 6, and under the control of limit switches r, s. A signal is given by a device 11 energized by a time relay 10 when the blower has operated for an abnormal period. An indicating lamp v is lit while the head is operating.

To prevent diverge of the output energy distribution lobe from the optical axis of a laser Q-switched by a rotated resonator reflector, one end of the resonator comprises a plurality of fixed reflecting surfaces Ml, M2, M3, M<SP>1</SP> 1 , M<SP>1</SP> 2 , Fig. 3, and a rotated Q-switching reflector M4, the arrangement of reflectors being such that when the optical system becomes sufficiently aligned for Q-switching to commence, radiation emitted from the active medium 1 on one side of a plane through the optical axis is reflected back to the other side of the plane and vice-versa. Thus an emitted ray RQ becomes a reflected ray JK. As the optical system alignment improves during the period of Q-switching the rays converge into parallelism along the optical axis as shown at SE and LM. Due to the symmetry of the optical system the lobe of output energy distribution lies along the optical axis. Modifications using fewer reflecting surfaces are described, Figs. 4 and 5 (not shown).
